摘要：

We report an observation of the strong dependence of the multiple (6<q <= 10) ionization cross section on the alignment of the molecular axis in collisions of highly charged Xe ions with N-2 molecules at an impact energy of 5.9 MeV/amu. Theoretical calculations based on the statistical-energy-deposition model well describe the experimental data.
